The 3D picture below is of Australia using track depth data to build it. Notice how the tracks are drawn over the 3D picture. Simply connect your depth sounder to P-Sea WindPlot 3D SeaBed Builder and you can build your own. It can also be used to update existing charts. Filtering is provided to reject bad depth data and depth can be automatically adjust using the built in tide program and/or height from a DGPS.

This P-Sea WindPlot users comment:Add another testament from Australia saying how impressed I am with Windplot's features and how its track handling capabilities keep me ahead of the competition!
